What I offer
Powerful web scraping solutions
End-to-end coverage: from a single dataset delivered once, to production pipelines running 24/7 on your cloud.
Custom

Data as a Service
Data as a Service
You tell me what you need; I deliver the data on a recurring schedule. No infrastructure to manage on your side.
- Daily, weekly, or on-demand refreshes
- Delivery via API, S3, webhook, or your data warehouse
- Monitoring and QA included — you get reliable data, not alerts

Why work with me
The expertise of a scraping company, with the speed of a senior engineer
I'm a senior engineer who spent years at Bitmaker, a web scraping company that served dozens of enterprise clients. I helped build Estela — the same open-source orchestration platform Bitmaker runs on today.
Now I work directly with clients. No sales layer, no account managers, no handoffs. You talk to the engineer who designs and builds your pipeline.
Source code ownership
Every spider I build is yours. Full code, full documentation, no vendor lock-in.
Battle-tested infrastructure
Kubernetes, Kafka, multi-cloud. Same stack used by the company I came from, proven at scale.
Senior engineering, directly
You get a senior engineer, not a sales rep. Faster scoping, clearer delivery, fewer surprises.
AI-augmented where it helps
I build internal tools (like Spider Factory) that combine LLMs with traditional scraping to ship faster.
Automate your data flow. Let's build it together.
Tell me about your target sites, your schema, and your delivery frequency. You'll get a concrete scope and timeline within 48 hours.
